Belt-Worn Device Alerts Workers for Unsafe Postures


The wearable Kinetic Reflex is designed to assist workers by alerting them regarding body postures

Majority of daily tasks require lot of bending, twisting or reaching that can cause complex spinal injuries. The Kinetic Reflex’s is equipped with an inertial measurement unit (an accelerometer/gyroscope combo). The Reflex can worn on the user’s belt or waistband while they are conducting daily tasks in a factory, warehouse or other setting. The wearable detects posture when they’re performing high-risk actions such as lifting objects by bending at the back instead of at the knees. Furthermore, the device provides user with a real-time alert by gently vibrating and displaying a warning on screen.

The Wi-Fi-equipped device transmits collected data to central computer-based dashboard at the end of each shift. The final data is reviewed by supervisors for workers’ safety habits. Moreover, dashboard displays how all of the workplace’s detected unsafe postures are distributed amongst different tasks, so action can be taken in areas of high risk. The device is water- and impact-resistant and it can be operated for 15 hours per charge of battery. Furthermore, the device can be used to set goals, which will help workers to stay below a given number of warnings each day. This feature allows workers to compete against one another, with an incentive being provided to whoever is shown to be the safest.

The Reflex was launched in 2017, and has reportedly been shown to reduce unsafe postures by up to 84 percent, along with reducing musculoskeletal injuries by 40% within 12 months of use and reducing reports of worker back pain by 56%. This month, Kinetic received US$ 4.5 million of seed funding, which should result in increased production and availability of the device. Workplaces utilizing the technology pay an annual fee of US$ 200 to US$ 400, depending on the number of devices being used.
